Is there a way to edit a shapefile's Item Description > Summary in ArcPy?

I can right click on the shapefile in catalog, select Item Description, then click edit... but I want to automate this in arcpy. I also want to keep the default metadata format. Screenshot below is example of default metadata format, with my manual edits to Summary (not done in arcpy).

With pure ArcPy the way to do this is to save a copy of the item's metadata to an XML file, modify it, then save the XML back to the original ArcGIS item. From the documentation:

Another approach is to use a Python script to update an item's
metadata content. The Python script must execute the same
geoprocessing tools as the model described above that processes
metadata using an XSLT stylesheet. The XSLT Transformation tool is
used first to save a copy of the item's metadata to an XML file using
the exact copy of.xslt stylesheet provided with ArcGIS Desktop. The
resulting XML file can be modified with a Python script. Then, the
updated XML document must be saved back to the original ArcGIS item as
its metadata using the Metadata Importer tool.

This arcpy_metadata package worked well! I am running ArcMap 10.6, and I converted my .py into a toolbox tool. Works like a charm, many thanks.

Small note: I had to install pip first, and then intall the arcpy_metadata package from command prompt to get it to run in my ArcMap tool. Initally, I was able to easily install the arcpy_metadata package in PyCharm and get it to run, but apparently the directory to which it was installed was not mapped by Arc(?). In case anyone has the same question, I followed the pip install instructions here (half way down the page): github.com/BurntSushi/nfldb/wiki/…
